help! Roof on freeform shape

Anonymous — Tue, 23 May 2023 12:53:06 GMT

looking to put a roof on this, not sure how or where to start, originally wanted to have a sort of corrugated metal roof.... any ideas?

1: Flat roof!
2: leave roof open - pretend is nudist colony fence
3: Use magic wand with auto-polyroof tool for slopes that follow the wall edges - will be wacky just like your plan. See attachment for the tool button.
4: extend walls to twice height, make single slope roof as you like and "trim to roof" for the walls.

And yes, a metal roof would work.

Arched complex profile wall and SEO to extended walls gives you some outside shelter.

arched complex profile wall trimmed with SEO to slab outline

Re: help!

Dwight — Sun, 28 Nov 2010 16:56:02 GMT

trimmed perpendicular - no new command necessary since SEO's stay live when the arch is rotated.

Assign your complex profile to a wall/beam tool and apply it using magic wand to a curve.

i have created this, and would like to know how to trim the 'roof' part so it overhangs the walls below by about 500mm ish.

i hope that makes sense, cheers, Joe

I'm back. Went to Seattle for the Comedy Festival:

Did you know that in Oregon school cafeterias they have stopped offering fruit punch because it sounds violent?

When you have a Complex Profile roof and irregular walls below, make a large rectangular slab at the wall base.Use the magic wand to cut a hole in the slab that is the shape of your building.

Use the perimeter expansion feature on the pet palette to expand the hole to suit your overhang size.

Use SEO "subtract with upward…" slab as operator, roof as target.

The roof trims to match the hole.

Try using OBJECTiVE. Referring to the attached image:

1. Draw a fill around the building perimeter (space-click on the walls or slab to magic wand one). Then expand the fill by the size of the eaves overhang.

2. Click the menu OBJECTiVE > Component > New Profile to create a new roof profile. Set the profile type to Elevation, and check the option to place the new profile over the fill.

3. After clicking OK, the tool will prompt for the direction of the profile bending axis. Click two points to set the bending direction.

4. Open the profile object settings, and use the horizontal bending parameter to set the deflection of the roof shape.

5. Extend the walls to at least meet the highest point of the roof. Then use SEO (with upward extrusion) to trim the walls to the roof.

6. The finished result in 3D.

The roof trims to match the hole.

A variation to this, as SEO's do not display correctly in the Floor Plan window, is to make the slab the shape of your roof outline, and use SEO Intersection with the CP roof. In plan you leave the slab layer visible to show your roof overhang, in 3D the slab is turned off and the roof is turned on.

Excellent!

That way, however, the slab and CP roof must actually intersect.
